Swedish Trangia 25 vs. Czech Dilo Varik alcohol cook sets. Approximately -8 oz. boil comparison. 

Trangia 25 Duossal set vs. Dilo Varik.
The Varik is very small, just over 8 oz. capacity.
The components on the Varik are included. A small pot, a burner base, a burner, burner cap, a lid, and 2 pot stands.
I only recommend the Varik for a cup of tea, coffee, or water for oatmeal based on the size.
